Input of the freely-programmable characteristic curve
The characteristic curve is defined by means of 21 restart points distributed uniformly over the set posi-
tioning range of 0 ... 100%. These are spaced at 5%. A freely-selectable stroke (range 0 ... 100%) can
be assigned to each restart (Fig. 31). The difference between the values of the stroke of two adjacent
restart points shall not exceed 20%.
To input the characteristic curve points (function values), the FREE menu item is first set. After opera-
tion of the MANUAL/ AUTOMATIC key the first restart point is input with the display 0 (%). After this
the next function value is 0 (%). A function value from 0 to 100% can be set using the arrow keys. After
confirmation using the MANUAL/AUTOMATIC key the next restart point is shown on the display etc. If
finally the MANUAL/AUTOMATIC key is pressed to confirm the function value for the last restart point
(100%), the program switches back to the CHARACT menu item.
Fig. 31 demonstrates an example of the free programming of a correction curve.
